1. Specification Indianapolis Indiana," have invented certain new and useful Improvements in Fuel-Feed ing-Device's, of which the following. is a specification accompanied by-drawings.

The invention relates to fuel-feeding appa apparatus forfeedingfinefuel. as coal or.

Another object of this invention is to afford provision for the regulation of the apparatus as desired. A

Further objects of the invention will hereinafterappear, and to these ends the'invention consists of apparatus for carrying out the above objects embodying the features of construction, combinations of elements, and arrangement of parts havin the general mode of operation substantial y as hereinafter fully described and claimediin this specifiings, in which- Figure 1 is a vertical sectional elevation of apparatus embodying the inventions Fig. 2 is avertical sectional elevation of a modified form, of apparatus.

nozzle and the "portion H' of supporting the the piping in such manner relatively to the furnace that theyrniay be moved vertically. As shown, the portion G of the piping is con- I nected to a slida'ble plate}. by means ofthe plate. in'guides K, connected to the'furnace. The

\ v fstruts J, and the nozzle iroiieets through'this through theng'ency ot'fiuidunder-pressure,

The plate itself is s id ably supported portion G of the piping is suitably connected, Q

as shown, to the ho per B.

According to both forms of this inventio the hopper B is provided with revoluble knives which in Fig. 1-' are shown carried by the revoluble disk 0; InFig. 2 the-knives are shown suoported independently of the disk 0; but trey are not shown vertically adjustable. 'luble, but, as stated, not vertically ad' stable, and the disk 0 is revolubl'e and. ad ust able, so that the knives and the disk have vertical movement relatively to each other and may be rotated in opposite direction, if ,desired, or the knives may remain stationary.

Any suitable means quay be provided in Fig. 1 for permitting vertical ad ustment of the disk 0, while at the same time affording 80 In Fig. 2 the knives are revoprovision for rotation 'of the same. 'In this instance the central shaft'P is connected to the disk 0 and provided with a collar Q, in the'groove R in the outwarclly-screw-t readed sleeves. -Said sleeve S is adapted to the inwardly-screwthreaded socket'T, carried. by the supports U upon the hop er. The upper portion ofthe sleeve S, as s own, is so constructed that a wrench may be used for rotating the sleeve in its-socket to adjust the vertical height of the disk 0. Rotation is imparted to the shaft P by any suitable means'as a pulley V, to

which. belting maybe ap lied. The disk 0,

5 the knives are aras shown, projects slight y edge ofthe hopperB, am ranged, as shown in Fig. 3, sothat the matebeyond the lower r al, as coal-dust, within the hopper is con- .tinual;ly;,fore ed out under-the. lower-edge of hopper by the action of thetk-mves If desired, an agitator Wof any suitabl structimi maybe provided 1 a "the'shalt' l.

at the lower end of the rod 4, extending Ion-- gitudinally within. the hollowed shaft 1 The rod 4 is suitably supported at its upper end upon the frame 5, and in this instance no provision is afforded for vertical movement of the knives. The disk is rotated, as before, by means of a suitable pulley and e belting which may be applied thereto. in Fig. 2 it w ll be seen that according to the position of the disk relatively to the knives a larger or smaller opening will be efi'orded between the disk and thelower edge of the hopper for regulating the flow of materiel, es in Fig. 1.

Obviously the invention may be embodied. in widely-varying forms, and some features of the invention may else be used without others.

Therefore, without limiting the invention to the construction shown and described n01 enumerating equivalents, I claim, and desire to obtain by Letters Patent, the following:

1. In an apparatus for feeding fuel, the

combination with a. hopper, of a revoluble disk forming the bottom thereof, knives within the hopper and in proximity to said disk,

means for adjusting said disk, and an agita-- tor within the hopper, for substantially the purposes set fort 2. In an apparatus for feeding fuel combination with a hop er, of e revoluble disk forming the bottom t ereof, knives Withv Lewis KQDAVIs.
